### Full HVAC System Replacement in Los Angeles
Replacing your entire HVAC system — both heating and cooling — is the right move when multiple systems are aging simultaneously, when one replacement triggers the practical need for the other, or when upgrading to heat pump technology that combines both functions. LC Heating & Air performs complete HVAC replacements throughout Los Angeles County with proper sizing, permits, and commissioning.
Overview
### Why Replace Both Systems Together
When your AC reaches 12–15 years old and your furnace is 15–20 years old, replacing both at the same time has significant advantages. You pay one mobilization cost instead of two. Modern split systems are designed as matched pairs — the AC condenser and air handler are engineered together. Mismatched components reduce efficiency and can create warranty complications.
### Heat Pump Systems: An Increasingly Popular Option
For many Los Angeles homes, a heat pump system is the best HVAC replacement choice. A heat pump provides both heating and cooling from a single system. In cooling mode it works exactly like a standard AC; in heating mode it extracts heat from the outside air and moves it inside — effective throughout the temperature range LA actually experiences. California's TECH Clean California program and federal tax credits make heat pump installation financially attractive right now.
### Sizing, Permits, and Rebates
Every system replacement includes a Manual J load calculation, a permit from the applicable building department, and documentation for all applicable rebates. We inspect your ductwork during the replacement assessment — installing new equipment on a leaky duct system wastes a significant portion of your investment.

Common questions about hvac replacement in Los Angeles
Should I replace my furnace when I replace my AC?
If your furnace is 12–15+ years old, yes — strongly consider it. You're paying one mobilization cost regardless. Installing a new AC on an aging furnace means you'll face furnace replacement within a few years. The economics usually favor doing both at once. We inspect your furnace during the assessment and give you an honest recommendation.
What is a heat pump and is it right for my LA home?
A heat pump is an all-electric system providing both heating and cooling. In heating mode it's 2–3x more efficient than resistance electric heat because it moves heat rather than generating it. LA's mild winters are ideal for heat pumps — they work most efficiently in moderate climates. Current California incentives make heat pumps particularly attractive.
How much does full HVAC replacement cost in Los Angeles?
A complete HVAC replacement (AC condenser, air handler, and gas furnace) in a typical LA home runs $7,500–$14,000 depending on equipment size, efficiency level, and ductwork required. Heat pump systems have similar costs. Available rebates can reduce the effective cost significantly. We provide a written estimate after the assessment.
How long does a full HVAC replacement take?
Most complete replacements in homes with existing ductwork are completed in one day — typically 6–10 hours. If ductwork repairs or modifications are included, it may extend to two days. We provide an accurate timeline in the proposal.
What rebates are available for full HVAC replacement in LA?
The best incentive programs include TECH Clean California (particularly for heat pump and all-electric systems), SCE appliance rebates for high-efficiency AC equipment, and federal Residential Clean Energy Tax Credits for qualifying heat pump installations. We identify applicable programs and handle the documentation.
Do I need to upgrade my electrical panel for a new HVAC system?
For traditional gas furnace and AC systems, panel upgrades are rarely required. For heat pump systems that run entirely on electricity, it depends on your panel capacity and the heat pump specifications. We assess your electrical service during the assessment and identify any upgrade requirements upfront.
Will new equipment work with my existing ductwork?
It depends on duct condition and design. We inspect your existing ductwork during the assessment and identify leaks, obstructions, or sizing issues. Most existing duct systems need at least some work to function optimally with new equipment. We include duct assessment and required repairs in the project scope.
How do you ensure the new system is properly sized?
We perform a full Manual J load calculation per ACCA standards before recommending any equipment. This calculation accounts for your home's specific insulation levels, window area and orientation, ceiling heights, and local design temperatures for your specific LA neighborhood.
